Constantia means big plots, old oaks, vineyards and horses, so pest control here is often as much about the garden and outbuildings as the house itself. Squirrels in the roof, rats around the stables and wasps in the hedges are everyday conversations in the valley.
Crawling insects in Constantia: what we see
Argentine ants trail in from the big gardens, and fishmoths like old wooden cupboards and boxes stored in outbuildings. Near the mountain edge, scorpions and rain spiders turn up in garages and pool rooms.
Many homes are large, older properties on generous stands, some Cape Dutch in style with thatched roofs, others modern with big glass walls and pool decks. Staff cottages, garages, stables and pool houses all add extra buildings that need checking. Thatch and exposed beams give rodents and borer beetles places that are hard to reach once they're established. The newer security estates have neater gardens but still back straight onto greenbelts.
How to tell you have a problem
- Someone in the house wakes with a small, red, sometimes blistered bite that was not there the night before.
- Cast skins and dead insects collect along skirting boards and in the backs of cupboards.
- Outside lights draw a cloud of moths and midges each night with webs built right around them.
- Fresh webs reappear in the same corners, window frames and eaves within days of being brushed down.
Something most people miss
People often kill rain spiders on sight, but they rarely bite and they eat cockroaches. If one wanders in, a container and a piece of cardboard will get it outside without any fuss.
How the treatment works
We start by identifying the species, because a rain spider on the wall and a nest of button spiders by the jungle gym call for very different responses. Webs and egg sacs are removed by hand or vacuum first, which takes out a surprising amount of the next generation. We then apply a residual spray or a fine insecticide dust into the places spiders actually live: roof voids, behind fitted units, wall cavities, garages, eaves and window reveals, keeping it away from where children and pets play. Where insects are drawing the spiders in, we treat or advise on that food source too, because spiders follow their prey. Finally we point out gaps around doors, vents and pipes that need sealing.

Keeping them out afterwards
- Keep stacked wood, bricks and old pots away from the house walls, because these are prime spots for button spiders.
- Fit fine mesh to vents and seal the gaps around pipes and under doors with sealant or brush strips.
- Brush down webs regularly and vacuum the corners and the backs of cupboards, which gets rid of egg sacs before they hatch.
- Swap white outdoor bulbs for warm yellow or LED ones so fewer insects gather, which means fewer spiders setting up around your doors.
- Shake out shoes, gardening gloves and clothes that have been left on the floor or in the garage before you put them on.
How much will it cost?
The cost depends mainly on the size of the property and how many outbuildings, garages and roof spaces need treatment. A house with a heavy insect problem feeding the spiders takes more work than one with a few webs in the corners. We give a free quote after a quick look or a WhatsApp photo, and contract clients get spiders covered as part of their routine visits.
Spider activity climbs from late spring and peaks in the hot, dry months from January to March, which is exactly when rain spiders come indoors and people start to notice them. Button spiders are most visible in summer around gardens and pools. In the wet winter months many spiders retreat into roof spaces and garages, so a treatment then catches them where they shelter.
Questions we get asked in Constantia
Can you stop squirrels getting into my roof in Constantia?
Yes, but the lasting fix is physical. We find where they are getting in, usually a fascia gap or loose ridge tile next to an oak branch, and advise on sealing it once the roof is empty; cutting branches back from the roof helps a lot.
Is the rain spider in my house dangerous?
Not really. Rain spiders are big and fast but rarely bite, and the bite is painful rather than dangerous; the kindest option is to catch it under a container and put it outside.
What should I do if someone is bitten?
Clean the bite, keep the spider if you can safely do so for identification, and see a doctor, especially for a suspected button or violin spider bite. Do not rely on a pest controller for medical advice.
Does a thatched roof in Constantia need special treatment for borer?
The grass itself is not what borers are after, but the poles and battens holding it up can be. We inspect the visible timber for fresh holes and dust and treat only if there is active infestation.
Do you come out to Constantia for spider control?
Yes. Constantia is part of our regular Southern Suburbs route, along with Bergvliet, Tokai, Plumstead, Diep River. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Will the treatment harm my pets?
We treat cracks, voids and roof spaces rather than open floors, and we ask that pets are kept out until surfaces are dry. We will explain any specific precautions on the day.
